Abstract

Single-crystalline LiMn₂O₄ hollow nanocones are synthesized via a template-engaged low-temperature lithiation reaction. When applied as cathode materials for lithium-ion batteries, they can deliver a high specific capacity of 127.1 mAh g^-1 at 0.1 C and the capacity still maintains 100 mAh g^-1 even at 50 C. After over 1000 cycles at 5 C, 94.8% of the initial capacity is retained.
